Ha, my new Model 3 phantom braked the first time on the trip home from the service center, which was only 10 miles. I doubt it had even gone over 10 miles on the odometer at that moment.
It's entirely possible it had more miles than 5 on the odometer when I picked it up. Officially the paperwork says 15, the associate who gave me the car said it was actually less, and the odometer isn't very prominent so I never even looked. Maybe it had 50 miles and was a reject ;). I should go check TeslaFi, since I reenabled that the day I bought the car. I confess that the only way I ever know how many miles my car has is when I see it on TeslaFi.
